Differences between 2 stroke and 4 stroke engines?
Two strokes have two cycles the piston go through intake/compression and ignition/exhaust where four strokes have four separate piston cycles intake compression ignition and exhaust.
Do you find carburetor in 4 stroke engines or 2 stroke engines?
Both 2-stroke and 4-stroke engines have a carburetor.
What is the difference between a 2 and a 4 stroke dirt bike?
Well with out boring you to death Ill give you the basic version. A 2 stroke engines piston on the down stroke pulls in fuel and air mixture on the way up it compresses mixture. At the peak of the stroke it is combusted forcing piston down. On the pistons up stroke the exhaust port opens and pushes out exhaust out. If you count the cycles there are 2 hence 2 stroke. The piston makes 2 cycles for every power cycle. The 4 stroke makes 4 cycles for every power cycle.
What does 2 cycle and 4 cycle engines mean?
A 2 cycle engine's piston cycle twice. One compression stroke and 1 exhaust stroke. A 4 cycle engine cycles four times before its exhaust stroke.
2 stroke vs 4 stroke?
On a 2 stroke engine, each cylinder fires every time the piston comes up. On a 4 stroke engine, the cylinder only fires every OTHER time the piston comes up. 4 stroke engines have 4 strokes: Intake, compression, power, and exhaust. 2 stroke engines complete these cycles in only two strokes of the piston by use of ports in the cylinder walls. 2 stroke engines usually produce more power for a given weight/size. But, in gasoline engines, 2 stroke engines are typically less efficient (use more gas) and have much higher pollution levels (note: some newer "direct injection" 2 stroke engines do much better on pollution levels than the typical 2 stroke)
What is the source of energy for the strokes other than power stroke in 4 Stroke engines?
There are intake and exhaust "cycles". A 2 stroke goes so much quicker because it it simply intake exhaust, generating power rather fast compared to the 4 cycle engines making power in the cycle half as often. The valving on 4 strokes allows for many things but they are never quite as quick as two stroke engines.
What is a 4 stroke outboard?
Combustion piston engines can have two different work cycles, 2-stroke and 4-stroke. 2-stroke tends to have a better power to weight ratio, but pollute more. A 4-stroke outboard is simply an outboard engine that works the same way as a car engine.
How are two stroke engines lubricated?
Two stroke engines are lubricated by mixing special two-stroke oil in with the petrol.
What are advantages of two stroke engines over four stroke engines?
There are a couple, less parts for one therefore lighter. Also, 2 stroke engines fire every time the piston comes to the top. Which means every stroke is a power stroke. 4 stroke engines fire every other time.
What kind of engines are most gasoline engines?
they are 4 stroke engines...
Do riding lawnmowers have 4 stroke engines?
All Riding Lawn Mowers are 4 stroke engines
Are the tug boat engines are two stroke or four stroke?
All tug boat engines are four stroke engines, because this engine responces quickly in relation to maneuvering this kind of boat in any situation.
